Cowardice and lack of faith

قَالُوا۟ يَـٰمُوسَىٰٓ إِنَّا لَن نَّدْخُلَهَآ أَبَدًا مَّا دَامُوا۟ فِيهَا ۖ فَٱذْهَبْ أَنتَ وَرَبُّكَ فَقَـٰتِلَآ إِنَّا هَـٰهُنَا قَـٰعِدُونَ

They said, "O Moses, indeed we will not enter it, ever, as long as they are within it; so go, you and your Lord, and fight. Indeed, we are remaining right here."

وَإِذْ قَالَت طَّآئِفَةٌ مِّنْهُمْ يَـٰٓأَهْلَ يَثْرِبَ لَا مُقَامَ لَكُمْ فَٱرْجِعُوا۟ ۚ وَيَسْتَـْٔذِنُ فَرِيقٌ مِّنْهُمُ ٱلنَّبِىَّ يَقُولُونَ إِنَّ بُيُوتَنَا عَوْرَةٌ وَمَا هِىَ بِعَوْرَةٍ ۖ إِن يُرِيدُونَ إِلَّا فِرَارًا

And when a faction of them said, "O people of Yathrib, there is no stability for you [here], so return [home]." And a party of them asked permission of the Prophet, saying, "Indeed, our houses are exposed [i.e., unprotected]," while they were not exposed. They did not intend except to flee.
